Abstract

General provisions and requirements for the development and application of a digital twin of a mechanical engineering product are established in the national standard, and the requirements defining the features of approaches to creating a digital twin of a product of a certain type are recommended to be established in the enterprise standard and/or in the technical specifications for development, which requires preliminary development. Research on digital twins of switching devices is at an early stage.

The purpose of the study is to identify the features and systematize the main approaches to the development of digital models and twins of a high-current switching device that are in demand at different stages of its life cycle.

Materials and methods. Approaches to the development of a digital twin have been developed based on the analysis and generalization of the provisions of modern Unified System for Design Documentation and computer modeling standards. Their features are developed for the design stage of the product itself, performed using reverse engineering technologies. A switching device with intelligent functions is adopted as an object of study.

Results. A structure of digital twins of a switching device has been developed, reflecting the differences in the composition by the type of main elements (physical object, electronic design document, computer models and information links) for different stages (phases) of the life cycle. Interrelations of modern standards have been identified. Initial mathematical models for solving the main design problems have been considered. At the same time, it is proposed to calculate the wear resistance of the switching device using proven empirical dependencies.

Model experiments to optimize the design of a switching device using mathematical and computer models are, in fact, virtual tests of digital models. Conducting virtual tests of prototypes and installation series samples seems inappropriate, since for switching devices, as well as for other devices of traditional purpose, all types and methods of testing are established by standards, which are mandatory and quite sufficient in the development and application of their intended purpose.

At the stages of production and operation, it is recommended to use simulation models and processing of information from sensors installed in the device.

Conclusions. When creating digital models, one should proceed from the provisions of the standards. It is sufficient to model physical processes based on known mathematical models. Model experiments based on these models, which are, in fact, a type of virtual tests, are advisable to use in design optimization. It is recommended to use the research results in the creation and application of digital models of high-current switching devices.
